I got a dental implant last year in November. My dentist promised me to finish procedure in about three month because the implant needs to heal first. So, I have been waiting. He started on my crown prep. in March. Now is October, and I don't have permanent crown yet because he always have excuses to move my app. I feel like he is using me to fill gaps between his patients, and he doesn't want to lose me because he needs my money. I am tired of it. I want to know my rights and if there is anything I can demand from him? Can I demand some money back because of his incompetence and because the procedure took him a lot longer time than he promised? Thank you.
